Huge silver cigar shaped craft glides low and slow over a populated suburban area in Mesa Az followed closely by a military fighter air

I was sitting in my parents pool facing south east. I looked up over my shoulder to see how much sun I was getting and saw a huge cigar shaped object sliding through the sky at no more than 200 feet up.  It was very shiny, seemless and big.  
It was heading south east at a slow steady rate.  There was no indication of a propulsion system.  It was the same in front as in back.  It confused my senses because it was so huge that it should have been making some kind of noise.  I couldn't even hear it displacing air.  
It was in view for no more than 10 seconds maybe less before the apartment complex next to my parents house obscured it.  About 15 to 30 seconds after it left my view a military jet fighter came right behind it low and slow.  The fighter validated my sense perception since it was obviously following the UFO and was loud.  It was very unusual for a fighter to be flying so low and slow over a populated suburban area.  I had never seen a jet fighter do that before.
Witness indicates that the date of the incident is approximate.  PD
